<p class="MsoNormal">Hi all<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a few dicing saws here that we are starting to get requests for dicing materials like InAs, InP, InGaAsP, etc. My question is about safety during dicing, like worries about airborne particles being breathed in. Our saws have water
spray and exhaust to mitigate this but normally meant for Si is this sufficient for the III-V materials as well? My other question is the waste water with wafer dust. If you do allow dicing of these III-V materials what do you do if anything about the water
with wafer dust going down the drain? Anything? Some sort of trap?<o:p></o:p></p>
